2a32/2a47 or obd P1017,
Car came to me after being towed to shop, apprentice could not open hood, so broke it open, found a no start, called a starter.
Shop foreman says to me to replace as he feels this is more up my ally than the apprentice.
Start car, notice long start, check engine on, rough idle and reduced power mode is clearly on.
Also, of note, a crank sensor signal code is also being thrown, but I have rpm PID data on scanner, and dash rpm also shows engine speed.
Here is where it gets weird.
Feeble trouble shoot chart I could find asked to see if scope is showing 1ms pulses @ 5v "KEY ON"
End of day arrives, I know europe cars will drain batt over night if key left in ignition, but scope is still connected, I am getting ready to close shop, but see vvt sensor in back probe is still generating a 1 ms volt signal on both pin the chart asked me to check for. Only thing I know before touching the car, half the inside was taken apart for hood cable replacement, and rear end is taken apart also for bat + removal, apprentice basically tore the car apart before I even started on it.
Hence why I got told to do the rest of the job. But now, this oscilloscope readiung has me confused, how is this vvt sensor generating exactly what BMW ask for spec "KEY OFF/in my hand"??
Any advice would be apreciated, if needed, I can produce snapshot and pics of key in hand 0-5v, 1ms intervals.
